Single Diodes Procurement Notes

Verify the specific HE3 suffix indicates AEC-Q101 automotive qualification rather than commercial grade. Confirm the _A-18 packaging code corresponds to 10,000 units per 13-inch reel. Ensure the ordering documentation matches the exact part number to distinguish from non-qualified variants.

Single Diodes Selection Notes

Select this component when AEC-Q101 automotive reliability is required alongside standard Schottky performance. The SOD-123 package offers a compact footprint suitable for high-density designs. Consider the 30 V reverse voltage limit and 300 mA current capacity during circuit planning.

Single Diodes Part Context

This part belongs to the BAT42W series of small signal Schottky diodes produced by Vishay Semiconductors. The HE3 designation specifically denotes RoHS compliance combined with AEC-Q101 qualification for automotive environments. The product line includes both commercial and automotive grades distinguished by their suffix codes.
